Foundrymax Rectangular 100×50×22mm / 10PPI 20PPI SIC Carbide Porous Ceramic Foam Filter

Foundrymax offers the 100×50×22mm Rectangular Silicon Carbide (SiC) Ceramic Foam Filter – a practical elongated filter format that provides double the length of standard 50×50 squares while maintaining the same 50mm width. This rectangular configuration offers increased filtration area without requiring a wider gating system, making it a versatile choice for foundries processing medium to larger castings across ferrous and non‑ferrous applications.

Manufactured from high‑purity silicon carbide, this filter delivers reliable performance at operating temperatures up to 1500°C, suitable for gray iron, ductile iron, aluminum, copper, and other alloy systems. The 10 PPI pore structure ensures excellent melt permeability with low flow resistance, effectively capturing slag, dross, and refractory particles while maintaining good pouring rates. The 22mm thickness provides robust mechanical strength, reducing the risk of breakage during handling and pouring.

The three‑dimensional reticulated network with over 85% open porosity ensures uniform pore distribution across the entire filter surface, delivering consistent filtration performance pour after pour. By removing non‑metallic inclusions early in the filling process, this filter helps improve casting density, reduce scrap rates, and enhance surface finish on finished components.

Key operational benefits:

• The elongated rectangular shape offers increased filtration area compared to standard 50×50 squares, suitable for larger sprue bases or wider runners.

• High open porosity maintains low back‑pressure, supporting stable mold filling and reducing turbulence.

• Excellent thermal shock resistance ensures the filter remains intact despite rapid temperature changes during pouring.

• Chemically stable – the filter does not react with molten metal or alter alloy composition.

Why Foundrymax for this rectangular filter?
As a direct manufacturer, we produce this 100×50 format in regular batches, ensuring consistent quality and dimensional accuracy. We offer the same footprint in alternative thicknesses (15mm, 22mm) and different PPI values (10, 15, 20, 30, 40) upon request, allowing you to tailor the filter to your specific casting weight and gating design.
